166 This function provides a simple search API on the bibliographic catalog
172 * $query can be a simple keyword or a complete CCL query
173 * @servers is optional. Defaults to biblioserver as found in koha-conf.xml
174 * $offset - If present, represents the number of records at the beginning to omit. Defaults to 0
175 * $max_results - if present, determines the maximum number of records to fetch. undef is All. defaults to undef.
176 * %options is optional. (e.g. "skip_normalize" allows you to skip changing : to = )
181 Returns an array consisting of three elements
182 * $error is undefined unless an error is detected
183 * $results is a reference to an array of records.
184 * $total_hits is the number of hits that would have been returned with no limit
186 If an error is returned the two other return elements are undefined. If error itself is undefined
187 the other two elements are always defined

2354 This function returns an array reference that contains the search parameters to be
2355 passed to the Z39.50 search script (z3950_search.pl). The array elements
2356 are hash refs whose keys are name and value, and whose values are the
2357 name of a search parameter, the value of that search parameter and the URL encoded
2358 value of that parameter.
2360 The search parameter names are lccn, isbn, issn, title, author, dewey and subject.
2362 The search parameter values are obtained from the bibliographic record whose
2363 data is in a hash reference in $matchpoints, as returned by Biblio::GetBiblioData().
2365 If $matchpoints is a scalar, it is assumed to be an unnamed query descriptor, e.g.
2366 a general purpose search argument. In this case, the returned array contains only
2367 entry: the key is 'title' and the value is derived from $matchpoints.
2369 If a search parameter value is undefined or empty, it is not included in the returned
2372 The returned array reference may be passed directly to the template parameters.
